Grounding
When operating the electrostatic gun, any
ungrounded objects in the spray location (people,
containers, tools, etc.) can become electrically
charged. Improper grounding can result in static
sparking, which can cause a fire, explosion, or
electric shock. Ground all equipment, personnel,
object being sprayed, and conductive objects in or
close to the spray location. Follow the grounding
instructions below.
The following are minimum grounding requirements
for a basic electrostatic system. Your system may
include other equipment or objects which must
be grounded. Check your local electrical code for
detailed grounding instructions. Your system must be
connected to a true earth ground.
• Pro Xpc Auto Controller: Ground the Pro Xpc
Auto Controller with a grounded power cord and
grounded socket. Also ground the controller with
the ground connection and ground wire.
• Pump: ground the pump by connecting a ground
wire and clamp as described in your separate
pump instruction manual.
• Fluid Bracket (for solventborne systems only):
ground the fluid bracket by connecting the bracket
ground wire to a true earth ground. Mount the
fluid bracket a distance behind the gun that can be
reached by a hose with a maximum length of 8 ft
(2.4 m).
• Fluid Tube (for solventborne systems only): ground
the fluid tube by connecting it to the grounded fluid
bracket.
• Fluid Hose (for waterborne systems only):the hose
is grounded through the conductive layer. Install
the hose as instructed in the gun manual.
• Electrostatic Air Spray Gun: ground the gun by
connecting the gun power cable to a properly
grounded controller.
• Air compressors and hydraulic power supplies:
ground the equipment according to the
manufacturer’s recommendations.
• All electrical cables must be properly grounded.
• All persons entering the spray location: shoes
must have conductive soles, such as leather; or
personal grounding straps must be worn. Do not
wear shoes with non-conductive soles such as
rubber or plastic.
• Object being sprayed: keep the workpiece hangers
clean and grounded at all times. Resistance must
not exceed 1 megohm.
• The floor of the spray location: must be electrically
conductive and grounded. Do not cover the floor
with cardboard or any non-conductive material
which would interrupt ground continuity.
• Flammable liquids in the spray location: must be
kept in approved, grounded containers. Do not
use plastic containers. Do not store more than the
quantity needed for one shift.
• All electrically conductive objects or devices in the
spray location: including fluid containers and wash
cans, must be properly grounded.
